You can try changing the ouput of the SDVENC via sysfs on Linux.

#echo composite/svideo > /sys/devices/platform/vpss/display2/output

hi Archith ！

the way of changing the ouput of the SDVENC via sysfs on Linux is ok !

but run the sdDisplay demo in the hdvpss_01_00_01_25 to display video from s-video interface

by default sdDisplay demo output video from SDVENC-composite interface

now how can i change the sdDisplay demo sources in order to operate s-video interface with CCS tools

thanks

Hi,

You can set the output to SVideo by using SET_VENC_OUTPUT ioctl. change aFmt of Vps_DcOutputInfo to VPS_DC_A_OUTPUT_SVIDEO to change output to SVideo.

Thanks,
